Hi, its me again... i should put a sleeping bag into this forum...

So, i get deeper into cord setups and i read in the manual about the 
preset cords, i wrote that i can assign midicontroler to fx sends, i 
did but nothing happens while turning the assigned controller. 
Is this entire feature only availiable if i use the xx7 as 1 track 
instrument? Anybody know? I use the xx7 as main instrument, so i work 
basicly in multi mode.
